Genes affected

UACA (HGNC:15947): (uveal autoantigen with coiled-coil domains and ankyrin repeats) This gene encodes a protein that contains ankyrin repeats and coiled coil domains and likely plays a role in apoptosis. Studies in rodents have implicated the encoded protein in the stimulation of apoptosis and the regulation of mammary gland involution, in which the mammary gland returns to its pre-pregnant state. This protein has also been proposed to negatively regulate apoptosis based on experiments in human cell lines in which the protein was shown to interact with PRKC apoptosis WT1 regulator protein, also known as PAR-4, and inhibit translocation of the PAR-4 receptor. Autoantibodies to this protein have been identified in human patients with panuveitis and Graves' disease. Differential expression of this gene has been observed in various human cancers.

The c.3758A>C (p.K1253T) alteration is located in exon 16 (coding exon 16) of the UACA gene. This alteration results from a A to C substitution at nucleotide position 3758, causing the lysine (K) at amino acid position 1253 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
